Filter Operation
1. Make sure the pump is primed according to manufacturer’s directions.
2. Be sure all valves are open on suction and discharge lines. Ensure
the air bleed valve on the filter lid is open and the lid lock ring is in
place and secure.
3. Start the pump. Close the air bleed valve when water is expelled.
4. To determine the correct operating conditions with a clean filter, check
that the pressure gauge reading is 80kPa or below.
5. Record the pressure gauge reading or mark the needle position on
the face of the pressure gauge.
6. Operate the filter for a sufficient time to circulate the total pool water
volume daily. The filter should also be operated at all times the pool is
in use and for about one hour afterwards. During winter, the
running time may be reduced. Filter operating requirements will vary
for spa applications, depending upon the system design, type and
size of spa. Consult your builder or spa supplier.
7. When the pressure gauge reading is 50 - 70kPa higher than the
‘clean filter’ reading as in (4) above, it is time to clean the element/s.
(See “Cartridge cleaning procedure”)
Cartridge Cleaning Procedure
When the filter gauge reading is 50 - 70kPa above the clean filter gauge
reading, cleaning the element cartridge is required. To perform the cleaning
procedure :
1. Switch off the pump.
2. Close isolating valves on suction and discharge lines where fitted.
3. Open the air bleed valve on the filter lid, unscrew the lock ring and
remove the filter lid.
4. Lift the element/s out.
5. In most cases the element can be easily cleaned with a garden hose,
using good velocity sprayed directly on the pleats.

Cartridge Re-Assembly Instructions
1. Install the cartridge/s & centre pipe so that it is located in the bottom
spigot.
2. Ensure the filter lid oring is clean, lubricated with oring lubricant and
located in the bottom groove of the lid.
3. Replace the lid and press firmly in place. Screw down the lock ring,
hand tight is sufficient - DO NOT OVERTIGHTEN.
4. Make sure the pump is primed according to manufacturer’s direc-
tions.
5. Ensure all valves are open on suction and discharge lines.
6. Start the pump.
7. Close the air bleed valve when water is expelled.
Water Quality
Maintaining balanced water chemistry is important to the life of your pool
pump. This pump is designed to be used with Pool & Spa water, balanced
in accordance with Langlier Saturation Index, with a pH level of between
7.2 and 7.8 and is regularly treated with a chlorine sanitising agent with the
level not exceeding 3000PPM.
Please consult your local pool shop regularly to have your water tested.
Filter Care
The Davey Cartridge Filter is the heart of the pool equipment installation.
Proper care and maintenance will add many years of service and enjoy-
ment to your pool. Keep the exterior of the filter clean using a mild deter-
gent and water.
Trouble Shooting
Reduced flow of water to the pool generally indicates the filter is ready to
be cleaned. Check the filter pressure gauge. (See section on ‘Filter Opera-
tion’). If cartridge cleaning is required, perform the steps described earlier in
‘Cartridge Cleaning Procedure’. If there is still reduced flow after cleaning,
check for blocked or plugged lines which could restrict the volume of water
entering the pool.
In the event of installation or operation difficulties with your Davey Filtration
Equipment, contact the supplier from whom the filter was purchased or your
nearest Authorised Davey Pool Equipment Service Centre. For assistance
in locating your nearest dealer contact the Davey Customer Service Centre.

Removal of the Filter
Should it be necessary to remove the filter, the following procedure should
be followed :
1. Switch off the pump and remove the plug from the power point.
2. Open the air bleed valve on the filter lid.
3. Close isolating valves where fitted.
4. Remove: – piping connection to the pump
– piping connection to the pool return
5. Remove filter.

Specifications
CLEARANCE TO REMOVE CARTRIDGE
NOTE: When making any enquiries about your Davey Filtration Equipment,
be certain to quote the Model Number from the nameplate on the equipment.
Danger HIGH PRESSURE. Relieve internal pressure before adjusting clamps
or opening filter.
Dirt & debris returning to your pool may indicate the pressure relief
valve has been activated. Remove & clean the element and check
that valve inside base of filter is free of foreign matter.
NOTE:
Algae, calcium, clay, sun tan oil and body oils can form a coating on
the element which may not be easily removed with normal hosing.
These materials can be removed by soaking the element in a de-
greaser and/or de-scaler. Your local Davey Dealer will be able to
recommend suitable products.
Failure to undertake regular maintenance may cause damage not
covered by warranty.
To avoid explosion and possible severe or fatal injury, filter pressure must
not exceed 280kPa. Do not test filter with compressed air. Check that all
clamps and fasteners are in good condition and are firmly secured before
pressurising system. Never adjust clamps or fasteners while filter is pres-
surised.
Caution! Do not add chemicals directly to the pool skimmer. Adding undi-
luted chemicals may damage pump and filter and void warranty.
DANGER - Hazardous suction. Do not block water entry into filtration
system with any part of your body as the pressure can trap hair or body
parts, causing severe injury or death. Do not block suction. Turn off
pump immediately if someone becomes trapped.
Small children using the pool or spa must ALWAYS have close adult su-
pervision.
Routine Maintenance tasks – to maximise the life of your pool equipment & personal
safety, use this checklist once a week. Turn pump off first.
a. Make sure that any pressure gauges are in working condition and the operating pres-
sure is within limits as specified on the product.
b. Make sure that each suction inlet, and main drain has a cover that is securely attached
and in safe working condition.
c. Make sure that all skimmer covers are securely attached and in safe working condition.
These should be replaced every 3 to 4 years.
d. Remove any obstructions or debris from the main drain cover.
e. Ensure the skimmer baskets and the pump hair and lint pots are free of leaves and de-
bris at least once a week.
f. Remove obstructions and combustibles from around the pump motor.
g. Make sure all wiring connections are clean and that all wiring and electrical equipment
is in good condition. Damaged wiring must be repaired or replaced by a qualified electri-
cian as soon as damage is discovered.
h. Check water balance and sanitiser levels at your local pool shop.
WARNING! Pump suction is hazardous and can trap and drown or disem-
bowel bathers. Do not block suction. Do not use or operate swimming
pools, spas or spa baths if a suction cover is broken, missing or loose.
Two suction covers and inlets must be provided into every pump to avoid
suction entrapment.
